- - If the previous instruction is a conditional branch
+ * If the previous instruction is a conditional branch
around the jump/bra, we may be able to reverse its condition
and change its target to the jump's target. The jump/bra
- can then be deleted. 1 byte

- mov abs24 -> mov abs16 2 byte savings
- Most instructions which accept d24 can relax to d16 2 bytes
- Most instructions which accept d16 can relax to d8 1 byte
+ abs24, imm24, d24 all look the same at the reloc level. It
+ might make the code simpler if we had different relocs for
+ the various relaxable operand types.
